                <h1>HTTP Basic Authentication (Basic Auth)</h1>
<p><strong>HTTP Basic Authentication (Basic Auth)</strong> is the simplest HTTP authentication method. The client performs identity
verification by including the username and password (Base64 encoded) in the HTTP request header. It is commonly used in
test environments, internal systems, or simple interface protection (it is recommended to use HTTPS in production
environments, otherwise the password can be easily stolen).</p>
<h2>Basic Principle</h2>
<ol>
<li>The client encodes <code>username:password</code> using Base64.</li>
<li>Adds the following to the request header: <code>Authorization: Basic &lt;Base64 encoded string&gt;</code></li>
<li>The server receives the request, decodes it, and verifies the username and password.</li>
</ol>
<h1>Usage</h1>
<h2>yaml Configuration</h2>
<pre><code class="language-yaml">security:
  HttpDigestAuth: # HTTP Digest Authentication
        globalCheck: true # Global check
        enabled: true
        username: admin
        password: admin
</code></pre>
<h2>Interceptor Validation</h2>
<p>Add the <code>@HttpDigestAuthCheck</code> annotation to the interface in use:</p>
<pre><code class="language-java">@GetMapping(&quot;/HttpDigestAuthCheck&quot;)
@HttpDigestAuthCheck
int HttpDigestAuthCheck();
</code></pre>
<p>The browser will prompt for account and password input.</p>
